I've included the dosage and frequency (every 4 weeks) information below. This information was produced by Flemming Labs, the manufacturer.
See the warning! I'm not sure about the withdrawl period. To be safe, I would call your county extension service or state animal health board.
CHICKENS - 4 to 6 weeks of age: for each 100 birds, use 1 fluid ounce (30 ml) of Wazine-17 in 1 U.S. gallon (3.8 liters) of drinking water.
Over 6 weeks of age: for each 100 birds, use 2 fluid ounces (60 ml) of Wazine-17 in 2 U.S. gallons (7.6 liters) of drinking water.
Treat broilers at 4 weeks of age and thereafter at 30 days, or as needed. Treat replacement pullets at 8, 12, and 16 weeks of age.
Warning
Do not medicate prior to slaughter within 14 days for turkeys and chickens and 21 days for swine. Do not use in chickens producing eggs for human consumption.
Restricted Drug - use only as directed
I'm personally not a fan of worming unless you have confirmed an infestation. Any vet should be able to do a fecal float test and determine the type of worms and then you can get the right wormer for the job.
Then again I'm bias and have not wormed a bird in 10+ years of raising them for meat and eggs. Just feel that unless you find them, it's an unecessary drug to use if you are going to eat them or their eggs.

Thank you guys for quic response, the reason of my question is: that I found a worm in the poo of one of the hens after I seen her acting wiered and I seperated her from the others and put her in one gage in the garage.
so do I need to give all of them the wormer? and when can I eat the eggs again?
Have you identified the type of worm? If so, and the wormer works for them, I'd treat the entire flock as they are likly to all have it. However, I want to say you'll have to discard eggs for two weeks before using eggs again, since that's how long to wait after being safe to eat the meat. Of course, it's just a guess, since there's not really money in industry to worm layer birds and test for residue, since they are caged.
If it's just one hen with worms... perhaps a fecal float of the flock could be done first, as the one that is sick may have more than one thing going on, thus worms have taken advantage of the situation and infected her.
